Samsung — Samsung s6 mobile quality

Address:

Dakshina Kannada, Karnataka, 575002

I purchased a Samsung Galaxy S6 On dec 25th 2015, however yesterday when i removed the phone from my pocket, i see a crack on the camera lens, i kept the phone inside the pocket for less than half an hour and also i have not put any pressure on the phone, when i went to service center they are asking me to pay 4000rs to to repair it, when i have paid 40000rs for the phone, i except the quality of the phone to be very good, the phone is just 4 months old, also i spoke to Samsung head office, even they are denying that there must be some force applied on the phone and know no force was applied and the only thing was i wore jeans and the pant fitting was tight, if the glass can break due to that reason for sure the quality is very poor and i want to raise complaint against Samsung company for providing low quality, i have attached the photo of the phone, so that you can make out if there was any force applied on the phone.

Thanks,
